Yes. You could try Vista's compatibility mode: in the file manager
(Explorer),
navigate to Maple's installer exe file. Right-click on it to invoke
the context menu.
Select Properties, then the Compatibility tab. Check Compatibility
mode and
select Windows XP or 2000.
Several customers have confirmed that the installer then works, but we
cannot
guarantee anything. Note that Vista is supported only from Maple 11.01
on.
If you would like to upgrade to the current Maple 12, which also runs
on 64-bit
editions of XP and Vista, please contact our sales team.

recently purchased Maple 11 for Linux and I installed it. I don't use
Windows Operating System therefore I can't tell. Ok, the question
is... Is Maple 11 written in Java? I see that the installer installs
the Java Runtime Environment. Is this software written in Java now? I
thank you in advance for your help.

'LinearAlgebra" package (in Maple 9.5, at least). It has a "Delete
Column" (or Row) facility, but not the opposite. Am I just missing
something in the help pages, or is that facility really gone?

how can one convert polynomic expression into sums, i.e., (a+b+c)^n into
sum(...,k=0..n) form (with n being posint)? convert(%%,sum) and
convert(%%,binom) seem to have another purpose...

Best,
Michael

I'm currently trying to get my head around General Relativity for a term
paper; the twist is that I'm dealing with an arbitrary amount of
dimensions, that is 4+d, where d is unspecified.

Now the maple tensor package does calculation with some fixed amount of
dimensions just fine, obviously. So currently I'm simply using 4+2
dimensions, the two extra ones representing the "arbitrary amount". As was
to be expected, this has come to bite me, since the actual amount of extra
dimensions comes up in the equations down the line, i.e. I have terms
like "2a + 2b", where the 2 in front of the b is actually the number of
extra dimensions which would change if I used some other amount and the 2
in front of the b is actually a regular coefficient. I guess you see the
problem now: Without actually doing all the calculations by hand, there is
no way to figure what numbers are dependent on the dimensions an what
numbers are not.

So I'm asking: Do you know any tricks that would enable me to specify
spacetimes (or manifolds) with arbitrary dimension?

regards,
/W

the following gives unfortunately an error in Maple12:

Sum(binomial(n,k)/binomial(2*n,k)/k!*(2*x)^k,k=0..n);
value(%%);
simplify(%%);

Can somebody shed some light onto what's going wrong there?

Is there an application with a better loglog plot?

Do you know the function which works tha same as coeff but not for
polynomials.

For example we have equation :



bb := (1 + alpha[1] h J + alpha[2] h J + alpha[3] h J )y[n + 1]
(x) =
(alpha[1] h J eta[2, 1] + alpha[2] h J eta[1, 1]) y[n - 1]
(x)
+ (1 + alpha[2] h J eta[1, 0] + alpha[3] h J + alpha[1] h J
eta[2, 0]) y[n](x)
+ alpha[1] h J eta[2, 2] y[n - 2](x)

And I want receive the equation

aa:=(alpha[1] h J eta[2, 1] + alpha[2] h J eta[1, 1]) ;


However when I wrte coeff(bb,y[n-1](x)) it does not work because my
expression is not of course a polynomial.
What function is an alternative ?

Thank you for help.
